Previously the input_data to create_usage_box was assumed to be a list of
3 chunks, one of each type: data, meta, sys. Now the list can contain any
number of entries and they will each be displayed. If the entries contain
the key "offset", then they will be shown at the appropriate location based
on that offset, with any gaps filled in by unused space ( they are thus
assumed to be in order ). Without the offset key, they will be displayed
in order, with no gaps.
